CLINTON A. HAGAIDONE, or wnsrnan SPRINGS, ILLINOIS, Assisivoaro INTER-NATIONAL HARVESTER. COMPANY or new JERSEY, A CORPORATION on NEW JERSEY.

To all whom it may concern Be it known that I, CLINTON A. HAGA- noxn, acitizen of the United States, residing at Vestern Springs, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Truck Mechanism for Harvesting-Machines, of which thefollowing is a full, clear, and exact specification.

My invention relates to means for supporting a harvesting machine, suchas a corn harvester, having a laterally projecting carrier connectedtherewith and extending stubbleward from the traction wheel; the weightof the carrier having a tendency to rock the harvester laterally, andconsists in providing a caster wheel mechanism that is yieldinglyconnected with the frame of the harvester in a manner to swing in avertical plane transverse to the line of draft of the machine; theobjectof my invention being to provide a mechanism that will maintain aproper balance of the machine and yieldingly accommodate itself to anuneven ground surface over which the machine may travel. These objectsare attained by means of mechanism, one embodiment of which isillustrated in the accom-' panying drawings, in which Figure 1 is a topplan view of the wheeled frame of corn harvesting machine having alaterally extending sheaf carrier and elevator connected therewith, andmy improved truck mechanism forming a part thereof;

Fig. 2 is a rear end elevation of Fig. 1; and v Fig. 3 is a sideelevation, on an enlarged scale, of a part of the wheeled frame of theharvester and the truck mechanism.

The same reference numerals designate like parts throughout the severalviews.

1 represents a part of the wheeled frame of a corn harvester comprisinglongitudinally arranged side members 2 and 3 upon the grainward andstubbleward sides of the machine, respectively, and a curved transverseportion 4 at the rear and preferably integral with the side members ofthe frame.

5 represents a bundle elevator attachment connected with the rear end ofthe wheeled frame and inclined stubbleward and upward. In the operationof the machine the elevator, with the additional weight of the materialbeing conveyed, will have a tipping effect upon the wheeled frame, andto Specification of Letters Patent.

counteract such effect is the object of my invention.

6 represents a substantially triangular frame comprising a rear bar 7extending laterally at right angles, more or less, to the line of draftof the machine, and having the grainward end thereof pivotally connectedwith the frame member 3 in a manner permitting the opposite end to riseand fall in a vertical plane relative to the wheeled frame; a frontmember 8 inclining rearward and stubbleward and having the grainward endthereof pivotally connected with the bar 3 in alinement with the axis ofthe rear bar 7.

9 represents a vertically arranged bearing block secured to thestubbleward ends of bars 7 and 8, and 10 a'longitudinally arranged barhaving opposite ends thereof secured to bars 7 and 8 near the inner endsthereof.

11 represents a caster wheel journaled upon an arm 12, that is providedwith a vertically arranged stem portion 13 journaled in the bearingblock9, and 14 represents an adjustable collar that receives the stem andregulates the operative length thereof.

15 represents a bracket member secured to a fixed part of the wheeledframe and provided with upwardly extending arms 16 that are connected bymeans of a cross pin 17,

and 18 represents links having the upper ends thereof provided withopenings that loosely receive the pin 17, the opposite ends of saidlinks being slidably received by openings in the bar 10, and 19represents compression springs encircling the bodies of the links andoperative between the bar 10 and shoulder portions 20 upon the links inI a manner to yieldingly resist an upward a caster wheel connected tosaid truck frame,

and automatic means for preventing said wheeled frame from tipping. I

2.'In a grain harvester, the combination of a wheeled frame, a truckframe pivotally connected to one side of said wheeled frame,

a caster Wheel connected to said truck frame,

link having one end pivotally connected to said wheeled frame and theopposite end thereof slidabiy connected to said truck frame, and aspring surrounding said link and actingbetween said frames to preventtipping of one of them.

5. In a grain harvester, the combination of a wheeled frame, a bundleelevator operatively connected to one portion of said frame tending tooverbalance and tip the same, and a truck frame connected to saidwheeled frame having means to automatically prevent tipping of saidwheeled frame.

In testimony whereof I aiiix my signature, in the presence of twowitnesses. e
